"It comes with any investing, it's volatile at times, especially cryptocurrencies," she said.

"The good thing is when it goes down, you can buy some more, and you know it's going to go up at some point.

"As long as you're calm and you don't let emotions run you when you're dealing with any sort of cryptocurrency, particularly Bitcoin, then you're safe."

How does Bitcoin work?

Right now, when we buy something online it goes through a bank or a credit company.

Bitcoin is a payment system that cuts out the middleman and the associated fees.

The idea came from an anonymous programmer, who in 2008 suggested that instead of a bank or a credit company recording every transaction in one central ledger, all of the users would record all of the transactions at the same time.

Any attempt to fool the community would be noticed and the payment would be rejected.

For the past four years, the Melbourne-based company has been accepting bitcoin to sell its products online.

"One customer bought a car with Bitcoin, the whole amount of over 30-thousand plus with Bitcoin and there's about 4 or 5 other customers that on a regular basis buy their parts and accessories using their Bitcoin accounts," David Brim from Tomcar said.

Others aren't so enthused about the virtual currency.

The head of JP Morgan said recently that cryptocurrencies such as Bitcoin are only fit for use by drug dealers, murderers and people living in North Korea.

And there are plenty of other skeptics.

"Australia in particular has been involved in buying and selling drugs on the dark web using cryptocurrencies," said Professor David Glance from the Centre for Software Practice at The University of Western Australia.

"Many are comparing the buzz around Bitcoin to tulip mania that hit the Netherlands in the 17th century."

Professor Glance said with such a volatile currency, investors should only buy what they can afford to lose.
